I MPROVE MENT IN MECHANISMS FOR CARD ING AND SPINNING WOQL, &c

Specification forming part of Letters Patent No. 173,290, dated February 8, 1876; application filed May 31, 1s75.

To all whom it may concern:

Be it known that I, JOSEPH HIBRY, of'Ohateauroux, in the Republic of France, have invented certain Improvements in Oarding and Spinning Machinery; and I do hereby declare that the following'is" a full, clear, and exact description of the same.

My invention relates to certain improvements which are designed more particularly for application to wool-spinnin g machinery, but which are equally applicable to machinery for spinning fibrous material of every description.

The invention consists, first,'in a novel combination of devices, whereby-I produce the produces the twisting of the thread; which thread, as fast as it is produced, passes out under the action of drawing-rolls, to be wound upon a bobbin.

The inventionconsists, further, in the combination, with said toothed or card-clothed roll, of a smoothing-roller, mounted upon the rotating plate, and arranged to revolve in contact with the fiber on the toothed or cardclothed roll, for the purpose of smoothing said fiber and giving a regular and uniform directionfto the same.

The invention consists, further, in the combination, with the rotating head and drawingrolls, of a guide for keeping the thread at the center of said head during its formation and passage out between the rolls.

An apparatus constructed according to my invention provides for the formation, at one operation, either with oilage or dry, and without any breakage, of a fine, smooth, and silky yarn, and. generally more regularly than with the ordinary spinning-machines. Each apparatus occupies a comparatively small space.

.of spinning.

expenditure of motive power.

"My invention assures a perfect regularity It prevents the formation of knots and waste of material, and lessens the It may be em-, ployedwith advantage in the formation of threads used in the manufacture of hosiery "and carpets by adapting the roll which carries the sliver to a mule-jenny furnished with this apparatus.

To enable those skilled in the art to which my invention appertains to make and use the same, I will more fully describe one mode of carrying it into eifect, reference being had to I the accompanying drawing, in which- Figure 1 is a side elevation of the apparatus. angles to Fig. 1. Fig. 3 is a face view of the preparing-roll and attached guide. Fig. 4 is a side view of the same. Fig. 5 is a view of the mechanism for imparting motion to the rolls.

The carded sliver is first wound upon a beam or roll, from which it is conducted, by a feed-roll, B, and pressure-roll G, into anopening in a casing, I, in which the rotating head is inclosed. The rotating head consists of a circular plate, and an attached preparing-roll and smoothin g-roll, and a central thread-guide. The circular. plate H is attached to a hollow axle, E, carrying a wheel or pulley,.M, by means of which it is rotated in the direction indicated by the arrow. To the plate H are attached two pins or studs,.J J, upon which revolve the preparing-roll and smoothing-roll. The pins or studs J are arranged in line with each other, and may be between the center v and circumference of the plate H, so that the preparing-roll and smoothing-roll may revolve with their faces near each other without con-- tact with the center of the plate. The preparing-roll F is geared to revolve in a direction opposite to that of the plate H, and hasv Fig. 2 is a sectional elevation atright The thread-guide consists of an arm, G, one end of which is attached to one of the pins J, and the other terminates near the center of the plate .El.

Opposite the center of the rotating head are two drawing-rolls, K K, the lower one of-which revolves in fixed bearings, and is driven by bevel-gearingN, operated by the driving mechanism of the machine, and the upper one is held in place by springs P, whereby it is permitted to rise in its bearings.

The circular plate H revolves at a very high speed, and the preparing-roll F very slowly, while the smoothing-roll D revolves faster than the preparing-roll, but not so fast as the plate H, and the drawing-rolls K revolve at the same speed as the preparing-roll. As the rotating head revolves, the card-clothed preparing-roll F at each revolution of the head I 7 takes off a quantity of fiber from the end of the carded sliver fed into the opening by the feed-rolls; and as said preparing-roll revolves in contact with the polished face of the smoothing-roll, which runs at a higher speed, and in an opposite direction, said smoothing-roll rubs and presses the fiber smoothly and uniformly on the preparing-roll in the form of a nap. The speed of the preparing-roll is so adjusted with relation to that of the plate H that the portion of fiber taken from the sliver at each revolution is laid immediately adjoining and connecting with the next preceding portion, so as to form a new sliver. Whenthe periphery of the preparing-roll has become almost entirely covered, the end of the new sliver thus formed is detached by means of a hook, and is passed under the guide G, and introduced between the drawing-rolls K K. As the rotation of the head continues, the sliver is twisted into a yarn, the guide G preventing its displacement from the center of the rotating head, and the drawing-rolls K K drawing it out as it is twisted. After leaving the rolls K the yarn is passed over a hook attached to the casing, and from thence to a bobbin, upon which it is wound.

The mechanism for imparting motion to, and regulating the speed of, the rotating head and attached rolls is shown in detail in Fig. 5, and partially in Fig. 2. Through the hollow axle E passes an arbor, S, which is driven by a wheel, L, at its. outer end, and carries a I gear-wheel, T, at its inner end. The wheel T drives a gear-wheel, U, which revolves on a hearing attached to the plate H. The wheel U drivesa gear-wheel, Z, attached to the pre- 'paring-roll F, and at the same time drives a pinion, V, secured to a wheel, X, revolving on a bearing attached to the plate H. The wheel X drives a pinion, Y, attached to the smoothing-roll D, and revolving therewith on the pin J. All these gears are so arranged with relation to each other and to the driving-power as to impart the proper speedto each of the working parts in the proper directions. The gears latter are covered by a plate, 0, for their pro tection from dust and floating fibers.

The speed of rotation of the plate H will, in most cases, continue uniform. The speed of rotation of the arbor S determines the degree of twist imparted. to the yarn, which maybe regulated to produce yarns of difi'erent degrees of twist by adjusting the speed of said arbor and its connecting-gears.

What I claim as new, and desire to secure by Letters Patent, is

The combination, with the feed-roll B, pressure-roll G, and the casing I, provided with an o 'ieningfor the passage of the sliver, of the rotating plate H, the preparing-roll F, and smoothing-roll D, carried by said plate, whereby the textile material is intermittingly taken in by the roll F, smoothed by the roll D, and twisted into a thread by the. rotation of the plate H, substantially as herein described.

2. The combination of the rotating plate H and hollow axle E, the arbor S and connecting-gears, and the preparing and smoothing rolls, substantially as. herein described.

HIBRY, JOSEPH.
